I have had Graphene OS for a month or so on a brand new phone. The phone has worked great so far, but recently, I have noticed that it sort disconnects from the 5g / 4g network without showing any signs of error.
While the phone appears to have coverage I cannot make or receive calls or text messages even though everything appears to be fine. This behavior persists until I reboot.
Any tips on how to troubleshoot would be greatly appreciated.
